rider be? For experiments, how is this data obtained?For a rider who outputs 300w (say a time trial where he/she travels at
approx. 26mph), the average pedal force with 175mm cranks at a cadence
of 90rpm would be:300/(.175*2Pi*90/60) = 182 Newtons (18.5 kgf) (41lbs)
Because of the cyclic nature of force application to the pedal, maximum
force could be as much as 37 kgf and minimum close to zero for this
example.Phil H
Nice formula Phil. Thanks all. -B.D
That's reasonable [even without knowing the 300Watt - which I've
always wanted to know], 'cos if the cyclist weighs 150 lb and
'stands' on the pedal s/he applies a force of 150 lbs so averaging it
out to one-third seems reasonable.
